+1 whatPwnfrnzy said. And: some minor COL problems (floating wheels) over the whole map. I had to rebuild the map IMG, and you should change the instructions to set the files into a subfolder, not directly in /maps. Its cleaner to deactivate or deinstall, or to backup. The radar is a nice idea, but bad since you only give the option to overwrite existing radar.img. You map is not the only map out there, you should provide (additionally!) the single files to include them manually to keep other map radar mods. I totally like where you placed the map. The "overall feeling" is quite good, resembles the IV landscape very good. At least the outside. I have not yet entered any secret area.
